Firefox 3.6 is about 15 percent faster

ComputerWorld tested Mozilla's latest edition of Firefox and concludes Firefox 3.6 is about 15 percent faster than Firefox 3.5. It's still a lot slower than Chrome and Safari though:

According to tests run by Computerworld, Firefox 3.6, which Mozilla launched on Thursday, is the third fastest of five Windows browsers tested. Firefox renders JavaScript three times faster than Opera 10 and more than four times faster than Microsoft's Internet Explorer 8 (IE8). It's also 14.5% faster than Firefox 3.5, the Mozilla browser that debuted in June 2009, a slightly larger speed increase than Mozilla has claimed.

But even with the JavaScript speed boost, Firefox 3.6 can't match Safari or Chrome. Safari is twice as fast -- and Chrome 4.0 nearly twice as fast -- as Firefox.

Safari edged Chrome for first place in the speed race, beating Google's browser by about 6.5%, a slightly smaller lead than in a November time trial that pitted Mac versions of the browsers against each other.
